How to dry traditional Chinese medicine materials?

Should Chinese medicinal materials be dried at low temperature or at high temperature? For example, chrysanthemums, honeysuckle, etc. are generally dried in the range of 40°C to 50°C. However, some medicinal materials with higher water content, such as astragalus, angelica, etc., may require higher temperatures for drying, usually in the range of 60°C to 70°C. The drying temperature of Chinese medicinal materials is generally between 60℃ and 80℃. The specific temperature requirements of different Chinese medicinal materials may be different.

During the drying process, the temperature must be kept constant and not too high or too low. What happens if the drying temperature is too high? If the drying temperature is too high, the quality of Chinese medicinal materials will be affected due to excessive drying, and problems such as discoloration, waxing, volatilization, and component destruction may even occur, resulting in a reduction in the efficiency of Chinese medicinal materials. Excessive drying temperature may also lead to a decrease in the appearance quality of Chinese medicinal materials, such as peeling, wrinkling or even cracking. What problems will occur if the drying temperature is too low? If the drying temperature is too low, the Chinese herbal medicines cannot be fully dried, mold and bacteria are likely to breed, causing a decline in quality and even deterioration of the Chinese herbal medicines. And it will also increase the drying time and increase production costs.

How to control drying temperature? The control of drying temperature requires professional Chinese herbal medicine drying equipment. Electronic temperature control is generally used to control the temperature, automatically adjust the temperature, humidity and wind force, and set drying parameters in time and stages to ensure the quality of traditional Chinese medicines.

In conclusion, the drying temperature of Chinese medicinal materials is generally between 60℃ and 80℃. Controlling the drying temperature is one of the important factors to ensure the quality of Chinese medicinal materials. During the drying process, the status of the Chinese medicinal materials needs to be checked regularly to ensure that the dryness of the Chinese medicinal materials meets the requirements. In order to ensure the drying effect and stability, drying equipment needs to be repaired and maintained regularly.
